/etc/init.d/scripts/bt p1 - This shell script handles the Bluetooth module and
is automatically started by the boot up sequence.
p1: defines what action should be done
< start >

initializes bluetooth port

starts bluetooth module

starts the bluetooth daemon

starts bluetooth services
(serial port service, obex ftp service)

starts bt_connect script
< stop >

stops bt_connect script

stops bluetooth services

stops bluetooth daemon

stops bluetooth module
< restart >

calls stop

calls start
/etc/init.d/scripts/bt_connect - - This shell script registers the Bluetooth address of
every device that is ready for pairing. It also
registers a password (default "0000").
